Description

Seat airbag system for vehicle and control method thereof

The present invention relates to a technology for protecting a passenger from a side impact of a vehicle by means of an airbag mounted on a seat cushion and a seatback.

BACKGROUND ART In general, a vehicle is provided with a safety device for protecting occupants in an accident such as a collision or rollover, and a representative example of such a safety device is an airbag device that directly protects the occupants seated in the driver's seat and the passenger seat of the vehicle.

In the case of a vehicle collision, compressed gas is instantaneously injected into the airbag by an external impact force, inflated at a high speed, and protects occupants from collisions. Along with the front airbag to prepare for a frontal collision, side airbags for preparing for a side-side collision of a vehicle are in general spread according to the international trend.

Conventionally, side airbags are mounted on both sides of a seatback in preparation for a side collision of a vehicle to protect the passenger's side.

However, due to the abnormal seating posture of the passenger, the conventional side airbag does not normally protect the passenger's side.

The matters described as the background art above are only for improving the understanding of the background of the present invention, and should not be accepted as acknowledging that they correspond to the prior art already known to those of ordinary skill in the art.
